“studies that replicate are cited at the same rate as studies that do not” [in psychology] "The majority (80%) of papers citing retracted research were published after the retraction date" [on covid] (continues below) https://t.co/bQI3T9sXt5 https://fantasticanachronism.com/2021/01/11/are-experts-real/

"Notorious fraud Brian Wansink racked up 2500 citations in 2020, two years after he was forced to resign"

The role of a manager is often defined from a business point of view only. But what about THE ROLE OF A MANAGER FROM THE EMPLOYEES POINT OF VIEW? (thread) 1/ Managers talk so clearly & concretely not to be misunderstood. They don’t clarify misunderstandings but prevent them.

2/ Managers give early and frequent feedback. This helps workers know when they're going off track before it's too late. It thus prevents frustrating surprises or wasting efforts on actions that cannot be rewarded.

A fascinating new paper on ergodicity. It's quite technical, so I took the freedom to explain here some of its findings and add on some of its applications. https://twitter.com/ole_b_peters/status/1528646949947285505?s=20&t=jgUMYPOPXHhNEb6UoMxAqA

The paper answers the question of "why do people cooperate by sharing resources"? Common answers include reciprocity ("I help you today so you help me tomorrow") or specialization ("I share my food and you share your tools").

COUNTERFACTUALS Does Omicron having lower fatality rate than Delta mean that it's milder? Does a peak in cases during a mask mandate mean that masks do not work? No. Let me explain it using counterfactuals (short thread)

Example 1: Does Omicron having lower fatality rate than Delta mean it's milder? Counterfactual: if Omicron was as severe as Delta, would its fatality rate be lower? Answer: yes, bc of the below Conclusion: Omicron's lower FR doesn't imply it's milder https://twitter.com/nntaleb/status/1475125312484749312

WHY DO MASKS SEEM NOT TO WORK? Because contagion still happens where people don’t wear them (restaurants, households, etc) Does it mean masks are useless? No! (thread)

Let me explain. First of all, a single unmasked exposure can be enough to cat the virus. This means that if I wear the mask 95% of the time than go eat at an indoor restaurant while cases are high, and I catch the virus, it doesn’t mean masks don’t work.

In our brain, there are not one but two decision-makers: The PLANNER (our cortex), which suggests what we *should* do And the GATEKEEPER (our basal ganglia), which decides whether to do it The interaction between the two determines most of human behavior (short thread) 1/9

As Autism Awareness Week just concluded, a summary of my posts on the topic. First, a visual metaphor to facilitate the understanding of how perception varies across the spectrum 1/4 https://twitter.com/DellAnnaLuca/status/1510297268867399683?s=20&t=a_R5FodxmchC2q7ETuwr6Q

THE ITALIAN 110% SCHEME Italy is wasting the money of Europeans on a poorly-designed scheme to improve the energetic efficiency of its buildings at excessive costs (up to 85%+ of building value) and earthquake resistance of buildings in areas with no earthquake risk. Thread

First, an example. I know of an apartment valued at 95k€ ($108k) for which the Italian government is paying for a 81k€ ($92k) intervention to improve energetic efficiency and re-do the facade. That’s 85% of the house value. The cost for the landlord: 650€ ($740).

Stopping elective surgeries Before mandating N95 for all hospital personnel Closing schools Before improving their air quality Closing domestic retail Before controlling international travel Asking for more or less mandates Without first wearing N95 We’ve lost our minds

The messaging should always have been, from minute one: “masks partially reduce risk; N95 more than surgical, surgical more than cloth, cloth more than none; depending on risk, higher grades are required” Instead we got black-&-white recommendations misleading & breaking trust https://twitter.com/bryan_caplan/status/1478409951097892868
